TIREHOLDER.

Application filed August 2.

To all whom it may concern:

Be it known that LINDSAY G. Furr- NER and Lewis S. PAUL, citizens of: the United States, and residents of the city of Johnstown, in the county of Camloria and State of Pennsylvania, (Whose post-office addresses are J ohnstown, Pennsylvania,) have invented. certain new and useful Improvements in Tire-Holders; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

Our invention relates to a tire holder adapted to receive and hold one or more pneumatic tires, preferably mounted on their rims. and ordinarily secured to the rear end or elsewhere of pneumatiotired vehicles.

Our invention consists generally of a tire holder eoinprisin a comparatively thin elastic annulus which may be normally of slightly conical outline or tapered to allow the rim to he slipped on and off and with an outwardly pro]ecting flange at the rear portion to form an abutment to prevent the rim from slipping over the same. Secured, to said elastic annulus are a number of llat arms or bars, pr ferably of metal. with lugs on their outer faces. between which lugs tire rims are adapted to be seated and retained in position thereby. These bars are preferably disposed at angles of 90 degrees around the annulus so that two of the same are opposite each other forming two onperating pairs. To one pair of opposite bars we pivotally secure threaded rods, which. near the center ot' the ring. are provided respectively with right and left threads which fit within corresponding internal threads in a cruciform center-piece.

The cruciform center-piece is adhpted to be rotated on said threaded bars so as to project them outwardly, causing the ring to expand and the flat lJlI-PS with their projections also to expand, and a. reverse movement of the threaded cruciform center-piece will draw the bars inwardly and also bend or spring the annulus or ring inwardly. o the other pair of flat bars we pivotally secure other members one of which has a plain end and the oi her is in the form of a. .U-shape member. the outer leg of the U being longer tlian the other. and these are of such length that when the contacting end Specification of Letters ratent.

1919. Serial ND. 314.914. of the cruciform member is pressed inwardly and engages within the end of the U-shape piece, it forces or expands the flat bars outwardly and also the ring or annulus so as to enlarge their diameters. In this manner one pair of projections can e drawn inwardly by the scnzzvthreads and the other pair is also drawn inwardly by releasing the toggle joint bars, whereupon a tire rim is slipped over the lug and the cruciform piece may be turned around. thus fol-ring one pair of the flat bars outwardly. and when this pair is in expanded position the end of the other member of the cruciform renter-piece is inserted within the U-shape portion of the link member and forces the other pair of ilat bars outwardly. thereby sec-urine the rim in position on the holder. "0 also providia staple and lock for securing the same to prevent theft.

Having; thus given a general deseription of our invention. we will now. in order to make the matter more clear. refer to the annexed sheet of drawings forming part of this speciiiratiou and in which like characters refer to like parts.

Figure 1 is a side elevation of our im proved tire holder; Fig. 2 is an and. elevation of the same: and Fig. 3 is a. horizontal transverse sectional elevation taken on the line i\---.\' of Fig; 1.

Referring now to the rharacters oi reforrnvv on the drawings:--l represents the outer pneumatic tire and rim mounted on our holder. 2 is the inner pneumatic tire and rim also mounted on the inner port-ion oi our holder. 3 is th flat annulus or ring which is provided with upturned or beveled inner flanged edge 4. I is a notch in the ring: to receive the threaded stem of the tire. 6 is a hole in the annular ring 3 to receive a boss of the wheel rim. some of which rims are made with such bosses in order to prevent their rotation on the telly. 7 are arms or extension brackets secured to the ring 3 by means of the rivets 8 which are countersunk on the outside and flush with the outer surface of the ring. as illustrated. 9 are lugs on the extension brackets adapted to abut against the lower hearing surfaces of the tire rims and approxinmn-ly lit the same. The extension brarkets are each pio \idcd with a bifurcated head 10 with hinge pins or rivets ll passing tbcretbrough. whereby the liulis 2d. the catch-lover l2 and re pivoted to said extension brackets. 1: is the link or catch-lever provided with u recess 13 therein formed by the bifurcated ends 1.4 and 15, the outer one libcing longer than the inner one 14 so as to form a substantial stop and bearing when the link. 12 is in its closed position, as illustrated in Figs. 1 and 2. i

The central or cruciform member is comprised of arms 16 and the right and left sleeve-nut portion 17 which is provided with internal screw-threads, one at one side being right-handed and the other at the other side lefbhanded to correspond with the threads on the links 28. A staple 18 is provided on the lower arm [6 While the lockingnrm or lever 19 is provided with a corresponding slot 26 to fit over-said staple, and these parts are secured together by the padlock 27. The locking-arm 19 is provided with ears 20 projectin r rearwardly from the same, having a pivot'pin 21 on which is .pivotally mounted the clamping arm 22,

which is provided with an internal screwthread in which is screwed an adjustable extension 24 of the clamping arm and Which T is locked in place by the iock-nut 25. This clamping arm is adjusted in length by means of the screw-threaded extension 24, the end of Which is adapted to contact with the side of the inner rim in order to hold it in place in only one tire is on the holder, as in case two tires are on the holder the outer one will hold the inner one from displace ment. In order toup'l padlock 27 is re of the cross-shape center-piece is the hand and pulled outwardl crossshape piece is turned a few revolutiohsf; which draws the links 28 inwardly and also? s rings the ring 3.21nd extensions 9 inwardly.

he disengagement of, the upper link 16 from the catch iever 12 also allows the upper and lowercxtensous 7 and portions of the ring 3 and attachments to springninwardly, thereby reducing ,the diameter of th'sparts Which engage the rim in such a"way that the rim and tire can be readily removed. A reverse operation will replace them.

We wish it understood that normally the conformation of the ring 3 and its.., attachments 7 are such that a tire can be ieadily slipped on or off the holder when the arms 16 are disengaged and when the links 28 are retracted.

Although We have shown and described our invention in considerable detail, we do not wish to he imited to the exact details of construction ,specified, but we may use such substitutions, modificiifions or eqmva lents thereof as are embraced .vithin the scope of our invention as pointed out in the claims.
